[linux-lvm] missing vg after reboot

[Michael <m_holschbach@yahoo.com>]

Hi!

I'm using LVM 0.9.1_beta7 on SuSE Linux 7.2.

I created a second VG (the other VG is detected by
vgscan on bootup) with only one PV and added some LV
to it. Later I added a second PV to the second VG and
i copied the old LV to new LV with stripes=2. All this
configuration was made with the lvm tool included in
yast from SuSE.
During reboot the system finds the first VG, but not
the second one, which was detected before, when only
one PV was assigned to it. I was using the second VG
before reboot with two assigned PV. 


*** output, which might be of interest:

Is there any way to fix the PV on hda2? I tried a tool
called uuid_fixer, but i only got the output "Illegal
instruction" back.
